Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
119 words
A method of preparing a femur for receiving an intramedullary femoral prosthesis, comprising: obtaining a patient-specific guide tool adapted for forming an anterior to posterior hole in the femur at an intersection of an intended vertical femoral cut and an intended calcar femoral cut; using the patient-specific guide tool to form the anterior to posterior hole in the femur; using the anterior to posterior hole to at least partially guide the vertical femoral cut in the femur; using the anterior to posterior hole to at least partially guide the calcar femoral cut in the femur; and using the anterior to posterior hole to at least partially guide a femoral broach for reaming the bone to accept the femoral prosthesis.
Claim 2
Independent Claim
119 words
A method of preparing a femur for receiving an intramedullary femoral prosthesis, comprising: obtaining a patient-specific guide tool adapted for forming an anterior to posterior hole in the femur at an intersection of an intended vertical femoral cut and an intended calcar femoral cut; using the patient-specific guide tool to form the anterior to posterior hole in the femur; using the anterior to posterior hole to at least partially guide the vertical femoral cut in the femur; using the anterior to posterior hole to at least partially guide the calcar femoral cut in the femur; and using the anterior to posterior hole to at least partially guide a femoral broach for reaming the bone to accept the femoral prosthesis.
Claim 3
Dependent Claim
29 words
The method of claim 1 , wherein the patient-specific guide tool includes an interior surface that substantially matches at least a portion of an anterior neck of the femur.
Claim 4
Dependent Claim
29 words
The method of claim 1 , wherein the patient-specific guide tool includes an interior surface that substantially matches at least a portion of a posterior neck of the femur.
Claim 5
Dependent Claim
29 words
The method of claim 1 , wherein the patient-specific guide tool includes an interior surface that substantially matches at least a portion of a femoral head of the femur.
Claim 6
Dependent Claim
15 words
The method of claim 1 , wherein the patient-specific guide tool includes a drill sleeve.
Claim 7
Dependent Claim
16 words
The method of claim 5 , wherein a height of the drill sleeve is patient specific.
Claim 8
Dependent Claim
16 words
The method of claim 1 , wherein the patient-specific guide tool includes a femoral cut guide.
Claim 9
Dependent Claim
16 words
The method of claim 7 , wherein the femoral cut guide includes a vertical cut guide.
Claim 10
Dependent Claim
17 words
The method of claim 7 , wherein the femoral cut guide includes a calcar femoral cut guide.
Claim 11
Dependent Claim
40 words
The method of claim 1 , wherein the patient-specific guide includes a vertical femoral cut guide, a calcar femoral cut guide and a drill sleeve positioned at an intersection between the femoral cut guide and the calcar femoral cut guide.
Claim 12
Dependent Claim
39 words
The method of claim 1 , wherein the step of using the patient-specific guide tool to form the anterior to posterior hole in the femur comprises advancing a drill bit through a drill sleeve in the patient-specific guide tool.
Claim 13
Dependent Claim
61 words
The method of claim 11 , wherein the step of using the anterior to posterior hole to at least partially guide the vertical femoral cut in the femur comprises leaving the drill bit within the anterior to posterior hole and using the drill bit to at least partially guide a saw blade in making the vertical femoral cut in the femur.
Claim 14
Dependent Claim
61 words
The method of claim 11 , wherein the step of using the anterior to posterior hole to at least partially guide the calcar femoral cut in the femur comprises leaving the drill bit within the anterior to posterior hole and using the drill bit to at least partially guide a saw blade in making the calcar femoral cut in the femur.
Claim 15
Dependent Claim
91 words
The method of claim 11 , wherein the step of using the anterior to posterior hole to at least partially guide the vertical femoral cut in the femur comprises removing the drill bit and patient-specific guide from the femur and placing a second femoral cut guide in contact with the femur, the second femoral cut guide having a projection that extends into the anterior to posterior hole, the second femoral cut guide further having at least one saw guide for at least partially guiding the vertical femoral cut in the femur.
Claim 16
Dependent Claim
30 words
The method of claim 14 , wherein the second femoral cut guide further comprises a second saw guide for at least partially guiding the calcar femoral cut in the femur.
Claim 17
Dependent Claim
21 words
The method of claim 1 , wherein the patient-specific guide tool further comprises at least one patient specific soft tissue protector.
Claim 18
Dependent Claim
68 words
The method of claim 1 , wherein the step of using the anterior to posterior hole to at least partially guide a femoral broach for reaming the bone to accept the femoral prosthesis comprises removing the drill bit and patient-specific guide from the femur and reaming the bone with the femoral broach, the femoral broach including an outwardly extending bar that aligns with the anterior to posterior hole.
Claim 19
Dependent Claim
17 words
The method of claim 17 , wherein the outwardly extending bar is removable from the femoral broach.
Claim 20
Dependent Claim
67 words
The method of claim 1 , wherein the step of using the anterior to posterior hole to at least partially guide a femoral broach for reaming the bone to accept the femoral prosthesis comprises removing the drill bit and patient-specific guide from the femur and reaming the bone with the femoral broach, the femoral broach including a visual marker that aligns with the anterior to posterior hole.
Claim 21
Dependent Claim
19 words
The method of claim 19 , wherein the visual marker comprises a hollow cylinder extending through the femoral broach.
